Does painted wood count as ‘treated’?
I’ve been reading around on the internet (with all associated caveats). Various sources suggest that engraving painted wood is safe, e.g., Full Spectrum Laser: https:/be OK to engrave?/www.youtube.com/watch?v=wkdsZh9bMnA&t=13sT
The main risk with paint seems to be volatile organics. On fully dry paint, this shouldn’t be a risk as, well, they are volatile…
What’s SLMS policy on this? Would it be OK if I engraved some wood that I have painted with a water-based acrylic emulsion with airflow after it is fully dry? Assuming that material safety data sheet doesn’t show PVC or other known corrosive/toxic additives?
